Description

Technical Field

[0001] This utility model relates to the technical field of film-spraying agent devices, and more particularly to automatic film-spraying agent devices. Background Technology

[0002] Compression molding equipment is widely used for pressing and molding various materials, featuring high efficiency and repeatability. However, during use, cleaning the mold often requires manual intervention. Manual cleaning not only increases the complexity of operation but also leads to mold damage or unstable molding quality due to improper operation. Therefore, improving the automatic mold cleaning function of compression molding equipment is of great significance, as it can increase production efficiency, reduce labor costs, and minimize the impact of human factors on product quality.

[0003] Traditional molding equipment typically comprises basic components such as a mold, heating system, pressure system, and transmission system. The mold is responsible for shaping, the pressure system provides the necessary pressing force, the heating system heats the material to a specific temperature, and the transmission system drives the mold to open and close and transports the material. These systems coordinate with each other through mechanical transmission to complete the material pressing process.

[0004] The main reason why traditional molding machines lack automatic mold cleaning functions is that their design does not fully consider the automation requirements of mold cleaning. Traditional machines typically rely on manual removal of residues from the mold, which is not only a time-intensive task, but also affects the quality of subsequent production if the mold is not thoroughly cleaned. The lack of automatic mold cleaning disrupts the continuity of the production process, increases downtime, and reduces production efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic release agent spraying device, which aims to improve the problem that the lack of automatic mold clearing function in traditional molding devices disrupts the continuity of the production process, increases downtime, and reduces production efficiency.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an automatic film-spraying agent device, comprising,

[0007] Symmetrical slides are arranged on both sides of the mold;

[0008] A hollow tube disposed on the slide rail, the hollow tube storing a film-clearing agent inside, and having multiple spray holes evenly distributed on its peripheral wall;

[0009] A motor connected to the slide drive drives the hollow tube to move at a constant speed in a straight line along the slide, so that the film-clearing agent is uniformly sprayed onto the mold surface through the spray hole under pressure.

[0010] As a further description of the above technical solution:

[0011] The slide rail includes a linear guide rail and a slider. The slider is fixedly connected to a hollow tube, and the motor drives the slider to slide along the linear guide rail through a transmission mechanism.

[0012] As a further description of the above technical solution:

[0013] The transmission mechanism includes a lead screw connected to the motor output shaft and a nut seat that is threaded into the lead screw.

[0014] As a further description of the above technical solution:

[0015] One end of the hollow tube is closed, and the other end is connected to the high-pressure liquid supply pipe through a rotary joint. The high-pressure liquid supply pipe is connected to the film-clearing agent storage tank and the pressure pump.

[0016] As a further description of the above technical solution:

[0017] The hollow tube is fitted with a replaceable flow guide cover, which has a flow guide groove corresponding to the spray hole, and the outlet direction of the flow guide groove faces the mold surface.

[0018] As a further description of the above technical solution:

[0019] The spray holes are evenly distributed along the axial direction of the hollow tube.

[0020] As a further description of the above technical solution:

[0021] The pressure pump is used to provide the pressure required for spraying the film-clearing agent.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this invention, the motor first drives the hollow tube to move in a uniform linear motion along a linear guide rail. Combined with the guiding effect of the spray holes evenly distributed on the periphery of the hollow tube and the guide shroud, the film-clearing agent is uniformly sprayed onto the mold surface. This design completely avoids the problem of uneven thickness caused by traditional manual spraying methods, significantly improves the demolding effect, reduces product surface defects, and increases yield and appearance quality.

[0024] 2. In this invention, the fully automated control of the film-clearing agent spraying process is achieved through the coordinated operation of the screw drive mechanism and the pressure pump. Compared with manual operation, this not only reduces labor intensity but also shortens the processing time of a single mold and improves production efficiency by precisely controlling the spray pressure and moving speed. Furthermore, the replaceable guide shield design facilitates quick adjustment according to different mold requirements, enhancing the versatility and flexibility of the device.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3 One embodiment of this utility model provides an automatic film-spraying agent device, comprising:

[0032] Slides 1 are symmetrically arranged on both sides of the mold;

[0033] A hollow tube 2 is configured on the slide 1. The hollow tube 2 stores a film-clearing agent inside, and its peripheral wall is evenly provided with multiple spray holes 3.

[0034] A motor 4, connected to the slide rail 1, drives the hollow tube 2 to move linearly at a constant speed along the slide rail 1, so that the film-clearing agent is evenly sprayed onto the mold surface through the spray holes 3 under pressure. The slide rail 1 includes a linear guide rail 11 and a slider 12. The slider 12 is fixedly connected to the hollow tube 2. The motor 4 drives the slider 12 to slide along the linear guide rail 11 through a transmission mechanism. The transmission mechanism includes a lead screw 5 connected to the output shaft of the motor 4 and a nut seat 6 threaded with the lead screw 5. One end of the hollow tube 2 is closed, and the other end is connected to a high-pressure liquid supply pipe 8 through a rotary joint 7. The high-pressure liquid supply pipe 8 is connected to the film-clearing agent storage tank 9 and the pressure pump 10. A replaceable guide shroud 13 is fitted on the outside of the hollow tube 2. The guide shroud 13 has a guide groove 14 corresponding to the spray holes 3. The outlet direction of the guide groove 14 faces the mold surface. The spray holes 3 are evenly distributed along the axial direction of the hollow tube 2. The pressure pump 10 is used to provide the pressure required for the film-clearing agent spraying.

[0035] Specifically, during operation, the automatic release agent spraying device uses a motor 4 to drive the lead screw 5 of the transmission mechanism to rotate. The rotation of the lead screw 5 drives the nut seat 6, which in turn pushes the slider 12 to slide along the linear guide rail 11. This causes the hollow tube 2, fixedly connected to the slider 12, to move at a constant speed along a straight path on the slide rail 1. Simultaneously, the pressure pump 10 pumps the release agent into the device through the high-pressure supply pipe 8. Under the pumping pressure, the release agent is sprayed out through the spray holes 3 evenly distributed around the hollow tube 2. The sprayed release agent is guided by the replaceable flow guide shroud 13 on the outside and the flow guide groove 14 corresponding to the spray holes 3, thus ensuring that the release agent is evenly sprayed onto the mold surface. Throughout the process, the motor 4 controls the uniform linear movement of the hollow tube 2, the pressure pump 10 provides the required spray pressure, and the flow guide shroud 13 guides the direction of the spray, ensuring that the release agent is evenly sprayed onto the mold surface. This automatic spraying process avoids the unevenness present in traditional manual spraying, improving both spraying quality and efficiency.

[0036] Working principle: When the automatic release agent spraying device is working, the motor 4 drives the lead screw 5 of the transmission mechanism to rotate, which drives the slider 12 to slide along the linear guide rail 11 through the nut seat 6. This causes the hollow tube 2, which is fixedly connected to the slider 12, to make uniform linear motion on the slide rail 1. At the same time, the pressure pump 10 pumps the film-clearing agent into the high-pressure liquid supply pipe 8. Under pressure, the film-clearing agent is sprayed out through the spray holes 3 evenly distributed on the periphery of the hollow tube 2. The sprayed film-clearing agent is guided by the guide groove 14 on the replaceable guide cover 13 on the outside, which corresponds to the spray hole 3, and is evenly sprayed onto the mold surface. The whole process is achieved by the motor 4 controlling the uniform movement of the hollow tube 2, the pressure pump 10 providing the spray pressure, and the guide cover 13 guiding the spray direction, so as to realize the uniform automatic spraying of the film-clearing agent and avoid the unevenness problem of traditional manual spraying.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
